Answer: B."Aplastic anemia affects all the blood cells, so the patient may report fatigue, have an increased respiratory rate and have problems with bruising. These patient’s also have impaired WBCs and ability to fight off infection, so a temperature greater than 100.4 F would be considered a medical emergency. The question is asking for what is most concerning or most serious of the signs and symptoms listed. Focus on what disease affects and how the patient would look if they had this condition. Then prioritize which signs and symptoms would be expected, and which would indicate a serious problem."
